 Except Bit=0 set to be used in closed loop, other Bit settings are for open loop.

FOC Bandwidth of Speed Observer

Settings
 Setting speed observer to higher bandwidth could shorten the speed response time but will create
greater noise interference during the speed observation. .

FOC Minimum Stator Frequency

Settings
 This parameter is used to set the minimum level of stator frequency at operation status. This
setting ensures the stability and accuracy of observer and avoid interferences from voltage,
current and motor parameter.
FOC Low-pass Filter Time Constant
Settings
 This parameter sets the low-pass filter time constant of a flux observer at start up. If the motor can
not be activated during the high-speed operation, please lower the setting in this parameter.
